Description
右シリンダ7は個々に燃焼面23および25を有する外側ピストン3(PR0)および内側ピストン5(PR1)を備えており、それらの2つのピストンはその間に燃焼チャンバ27を形成している。左シリンダ8はそれと同様に、個々に燃焼面24および26を有する外側ピストン4(PL0)および内側ピストン6(PR1)を備えており、燃焼チャンバ28を形成している。2つの外側ピストン3および4はスコッチヨーク(scotch yoke)101によって互いに剛的に接続されている。2つの上内側半割ピストン5aおよび6aはスコッチヨーク103によって共に剛的に接続され、2つの下内側ピストン5bおよび6bはスコッチヨーク104によって共に剛的に接続されている。好適な実施形態において、アセンブリを組み立て可能にするために、2つの内側ピストン/スコッチヨーク/シリンダ軸を通って且つクランクシャフト軸に直交した割れ目を有する半割ピストンは、結果的に共に剛的に固定され、それと同時にピストンリングシールのグループ17および18を捕捉している。
図3はクランクシャフトの一回転にわたった本発明のエンジンの動作を示している。図3(a)〜3(m)は30°回転ごとのピストン位置、スリーブバルブならびに関連した排気及び吸気ポート位置を示している(図3のクランクシャフトの回転は矢印で示されたように反時計回りであることを記しておく)。クランクシャフト角度φは図番の右側に示されており、ADC(死点後)と付されている。それは、左右のピストンが同時にそれぞれIDC(内死点)およびODC(外死点)となるからである。吸気ポートINおよび排気ポートEXにおける矢印は、ポートが開いていることを示している。
2ストロークエンジンにおける排気および吸気ポートの非対称タイミングは、大河の重要な利点をもたらす。排気ポートが吸気ポートよりも前に開いた場合、排ガス内のエネルギはターボチャージャによってより効果的に回収されることが可能であり、排気ポートが吸気ポートよりも前に閉じた場合、シリンダはより効果的に過給され得る。
多くのエンジン形態において、バランスは4,6,8またはそれ以上のシリンダを備えることに依存しており、シリンダは個々のピストンによって導かれる自由マスフォース(free-mass forces)を打ち消すように配置されている。対向回転ウェイト(Counter-rotating weights)もしばしば取り入れられ、それが複雑さを加えて、エンジンの質量および摩擦損失となる。本発明の利点は、複数シリンダエンジンが複数の2シリンダエンジンを並べて配置し、それらのクランクシャフトを全体的に連結することによって形成されてもよいことである。連結は、オペレータまたはロジック制御の下のクラッチとしての手段等によって行ってもよく、低負荷時に必要とされない場合はシリンダの組が切り離されることが可能であってもよい。現実にあるエンジンは、部分的な負荷で稼動しているがシリンダがクランクシャフトに接続されたままであり且つピストンがシリンダ内で移動し続けており、したがってエンジンの寄生性の摩擦負荷が継続している場合に、全シリンダ数未満で使用される
上記の事項は本発明の特別な実施形態の詳細な記載である。開示された実施形態からの逸脱は本発明の範囲内であってもよく、明確な変更が当業者には考え付くだろう。本明細書は、発明が表題を付けられた保護の範囲に、過度に狭く解釈されるべきではない。
